A small object has an angular diameter of 0.50$^{\circ}$.When viewed through a magnifier,it has an angular diameter of 8.0$^{\circ}$.What is the angular magnification in this case?
A) 4.0
B) 8.0
C) 16
D) 32
E) 8.5

We can use the formula for angular magnification:
Magnification = angle subtended by the image / angle subtended by the object

In this case, the angle subtended by the object is given as 0.50 degrees, and the angle subtended by the image is given as 8.0 degrees. So the angular magnification is:

Magnification = 8.0 / 0.50 = 16

Therefore, the answer is choice C) 16.
